It's been 24 days staying at Sofyan, the AC remote is dead because the battery is dead, call housekeeping asking for the battery, the person came, opened the room door a little, gave the remote but asked to come in, said he wanted to check the remote, when he came in it was very slow and unclear until finally I kicked him out, should have replaced the battery outside the room door, give it back to the guest to try, if it still doesn't work then come in to check the remote, why, this is before he even wants to come in, he wants to replace it inside but it's unclear.
